Promotional picture

Sometimes, before an episode of Futurama is aired, a promotional picture (or promo pic for short) is released. These show a key aspect of the episode, either drawn in a different style to what is shown in the show, or directly taken from it, in the form of stills. Over time, less and less promo pics were released, until Season 3 which only had four and an all-time-low of three pictures released for Season 4.
